Context of Lesson:
This is the last day of the unit. In this class the students will be taking an exam on the whole unit on covalent bonds and molecular geometry.

Opportunities to Learn:
Depth of Knowledge:

  • Level 1
    • Identify the number of elements in a compound.
    • Identify characteristics of ionic and molecular compounds.
    • Define the octet rule.
    • Draw a lewis dot diagram of compounds with 2-5 atoms.
    • Identify if a covalent bond is single, double, triple, or coordinate covalent.
    • Explain why compounds are shaped the way they are using VESPR theory.
    • Draw the molecular geometries of molecules.
    • Describe how electronegativities determine the distribution of charge in a polar molecule.
    • Label the positive and negative dipoles in a polar molecule.
    • Label a molecules bases on what types of intermolecular forces it contains.
  • Level 2
    • Describe why a compound contains a single, double, triple, or coordinate covalent bond.
    • Determine the molecular geometry of compounds.
    • Compare the strength of intermolecular forces to ionic and covalent bonds.
    • Organize 3 compounds in order of increasing bond strength.
    • Describe how oxygen atoms are bonded in ozone.
    • Organize 3 compounds in order of increasing bond strength.
    • Organize 3 compounds in order of decreasing bond dissociation energy.
  • Level 3
    • Differentiate between the melting and boiling points of ionic verses molecular compounds.
    • Hypothesize on what types of shapes a molecule can have.
    • Draw Conclusions about the shapes of molecules.
    • Differentiate between the different intermolecular forces.
    • Assess the effects of bonding and molecular geometry on a molecules chemical properties.
  • Level 4
    • Apply the octet rule to a molecular compound.
    • Apply concepts to analyze the reasons why molecules can form different shapes (repulsion, lone electron pairs, etc.)

Prerequisite Knowledge:

  • Bonding
  • Periodic Table
  • Molecular Geometry
  • Bond dissociation energy/resonance
  • Lewis structures
  • Intermolecular forces

Plans for Differentiating Instruction:
The exam will have illustrations as well as the normal text so that the visual learners will be able to see diagrams which will help them.

Accommodations and modifications:
The students that need some addition accommodations will be given extra time if needed. Some students may also get an edited exam which has fewer answer choices and/or some topics left out.

Environmental factors:
The students will be sitting in rows.

Materials:
